Abstract

In order to provide a sheet postprocessing device which positively prevents an uneven image from occurring without using any means that spoil the appearance when a set of sheets is ejected onto the ejection tray, and which stacks sets of sheets without disarray, in the present invention, after sheets have been ejected from the copying machine and have been subjected to a stapling operation that is one of postprocessing operations, the sheets are ejected onto an offset tray by an ejection roller. The ejecting rollers are provided with a lifting mechanism for lifting the leading portion of the set of stapled sheets with regard to the ejecting direction.
